5 Possible Reasons Why You Found Mold Growing on Walls in Your House

Published February 18th, 2020 by Devteam

Mold is a commonplace household event, but also a health hazard. Everyone reacts to mold differently, but it may cause health problems for you and your family. 

That's why it is important to identify sources of potential mold and figure out what causes mold to grow in your home. 

If you see mold growing on walls, take care of it immediately to prevent any adverse effects.

Read on to help identify 5 major reasons mold is on your walls.

1. The Humid Weather 

Humidity is a major cause of mold growth on your walls. With very humid weather comes a lot of moisture in the air. When it rains or is humid for many days in a row, you may notice dark stuff growing on your wall.

That stuff is mold!

If you live somewhere with high humidity, it could become a recurring problem. 

To try to combat high humidity, use an air conditioner or invest in a dehumidifier. Both of these will help keep your humidity levels low. Aim for between 30% and 50% humidity.

2. A Leak

Whether it is your window, pipes, or roof, a leak is a common reason to find mold on your walls. 

Water leaks that are out of view, like in your wall, can be especially dangerous. By the time you find the leak, mold is likely grown around the pipe or leaky spot before it comes to your wall. Having an especially damp area will cause mold to worsen.

If you notice water damage on the ceiling, it is likely that you have a leaking roof, or it may be a product of poor ventilation. 

In order to maintain water leaks and subsequent mold, regularly check your attic or roof for any potential leaks. Keep your pipes regularly maintained, quickly fix any leaks, and check windows for cracks. 

3. Flooding

Any situation with excessive moisture can cause mold to grow on walls.

Wet areas are more prone to grow mold. If you have flooding, keep an eye out for mold growth.

If you have flooding, especially regular flooding, it is essential that you handle it to prevent any further damage to the wall surface and interior. 

4. Poor Ventilation

Do you take hot showers? Ever notice mold growing on your bathroom ceiling or walls? Poor ventilation can be the culprit.

Whether you take steamy showers or have another room in the house that is poorly ventilated, it is a hot spot for mold. 

Try to use a fan or dehumidifier in rooms that are already poorly ventilated. Every time you shower, use the fan to prevent mold from growing. 

5. Wet Clothes

Leaving wet clothes around can cause mold to grow on the walls. Yes, really!

Also, drying clothes indoors causes moisture to escape in the air and increases humidity. If the room is not properly ventilated, washing your clothes can actually be a cause of mold in houses.
